Sideband fingerprint of the Leggett mode in terahertz two-dimensional coherent spectroscopy of multiband superconductors
Silvia Neri, Ryo Shimano, Dirk Manske +1
Collective modes of the superconducting condensate encode fundamental information on the pairing interaction, yet their direct detection remains experimentally challenging. In mult…
Quantum fluctuations and the emergence of in-gap Higgs mode in superconductors
Sida Tian, Naoto Tsuji, Dirk Manske
We extend the well-established action of the Higgs mode in -wave superconductors to include quantum fluctuations (QFs). We find that already one-loop quantum corrections to the…
Collective mode spectroscopy in time-reversal symmetry breaking superconductors
Silvia Neri, Walter Metzner, Dirk Manske
Time-reversal symmetry breaking (TRSB) superconductors show a rich collective mode spectrum. In general, collective excitations in superconductors can provide crucial information o…
Coupling of Higgs and Leggett modes in nonequilibrium superconductors
H. Krull, N. Bittner, G. S. Uhrig +2
Collective excitation modes are a characteristic feature of symmetry-broken phases of matter. For example, superconductors exhibit an amplitude Higgs mode and a phase mode, which a…
Signatures of nonadiabatic BCS state dynamics in pump-probe conductivity
H. Krull, D. Manske, G. S. Uhrig +1
We theoretically study the pump-probe response of nonequilibrium BCS superconductors coupled to optical phonons. For ultrashort pump pulses a nonadiabatic regime emerges, which is…
Electronic and phononic Raman scattering in detwinned YBaCuO and YCaBaCuO: s-wave admixture to the -wave order parameter
M. Bakr, A. P. Schnyder, L. Klam +5
Inelastic light (Raman) scattering has been used to study electronic excitations and phonon anomalies in detwinned, slightly overdoped YBaCuO and moderately overdo…
Evidence for the formation of magnetic moments in the cuprate superconductor HgCuBaCaCuO below seen by NQR
H. Breitzke, I. Eremin, D. Manske +2
We report pure zero field nuclear magnetic resonance (NQR) measurements on the optimally doped three layer high--compounds HgBaCaCuO and HgBaCaCuO(F) with 134 K. Abo…
